Rated 1.0 out of 5.0 by Upset Very Dissapointed: Milky White Haze
We purchased and installed a very nice flat black mailbox from Home Depot. We were encouraged to protect it with the Rustoleum Flat 2x Matte spray. The final result was a very unprofessional, ugly, white milky finish. Areas on top of the mailbox are peeling off. I called Rustoleum and was told there was possibly too much humidity in the air. According to these reviews, this is happening quite often. I wish I would have read these reviews before ruining our mailbox.
I have been told to sand it off with 180 grit sandpaper and to start over. This product should be re- examined. I really regret using this product.

This is a $4.00 quick fix, not a professional, or even an intermediate solution, which will cost about twice as much at least, not dry as quickly, and require more coats and care. The haze comes from humidity and temperature variances and over-application. In some instances I've seen the haze dissipate as the paint cures, and in general, it's best used in a controlled environment and in thin, even coats. I'll admit that it's not the most user friendly product, but it's fast and cheap. Just make sure the surface is clean, that it matches the ambient temperature (to avoid condensation that'll cause haze), that the ambient conditions don't change drastically during curing, and that it's not over-coated. If a white haze does show up, and is not severe, I'd recommend wiping it down with mineral spirits after curing, before panicking and sanding things of, or top coating with a semi-gloss of the same type which'll penetrate somewhat and might mitigate the haze.
It doesn't offer much scratch resistance, but I don't see where it says it does. Table tops and other heavily used items require more high end specialized finishes like polyurethane, enamel, epoxy and the like.

This product is HORRIBLE!!!!!! I spent weeks working on a special wedding sign for a friends sister and when I used this product it left a milky white haze!!!!!! I am sooooo upset about this!!!!! I have tried sanding it down some, hoping it would get rid of the haze. It helped some. Hoping when I go over with a different product it will bring some life back to the sign. If not its a start over project UGH!!!! Don't use this product!!!!

I ruined a new table by using this product (white haze and paint peeling off). Stay away from it.

Rated 1.0 out of 5.0 by Aldo Left milky uneven finish
I’m so upset I’m shaking. This made an absolute mess out of my project. Left milky uneven finish. Looks like someone dipped it in milk, and left it dry. I wish I had read the other reviews before I used this. A week of sanding, priming, top coating down the drain. Now I can look forward to waiting 2 days for this to dry so that I can start over. I can’t tell you how upset I am.

I spent a week doing a special custom paint-job on a toy, then went to seal it. When it dried, it was COVERED in a milky white film. I know have to COMPLETELY restart the project, thanks to Rustoleum. They should pull this garbage off the market IMMEDIATELY!

I bought the matte clear to paint over some flat black and all I get is a white haze over the paint. Now I have to go repaint everything.

I would not recommend this to anyone looking for a nice finish. It dries quickly but leave a white milky like stain in places where one may place a little, and I mean little, too much paint Ruins appearance of your work, and you may, as I am doing, remove the paint and start over. I would recommend the clear . Stay away from this product unless you completely sure this is what you want.
